Hello, so glad to find others like me. Doc believes I have subclinical PA. I have parietal cell antibodies, but not IFA. I know that doesn't eliminate PA, but blood looks great otherwise. I've been getting twice a month B12 shots for a year. Mostly feel great, except now some stomach issues. Question about my parietal cell antibodies-- latest blood work shows the level at 49. How does that rank? Thanks!
